node minimum age |
With records from the Torrejonian, the minimum estimate of Adunator can be tied to the top of the Danian at 61.6 Ma ± 0.0 Myr (Gradstein et al., 2012, p. 400; Woodburne, 2004).
node maximum age |
The soft maximum date is based on the divergence of Eutheria from other mammals in the late Jurassic, represented by Juramaia (Luo et al., 2011). This taxon is represented in the Daxigou site of the Tiaojishan Formation, Liaoning Province, Northeastern China, and has been constrained by radiometric dates to derive from deposits of just over 160 Ma in age (Luo et al., 2011). The equivalent marine stage is the Oxfordian (Gradstein et al., 2012), with a lower boundary of 163.5 Ma ± 1.1 Myr, and thus 164.6 Ma is a soft maximum.

Adunator is a member of Erinaceomorpha, according to phylogenetic analyses by Novacek et al. (1985) and Smith et al. (2002), and so is a nested within crown Lipotyphla.
